. VERTICAL FIBER GROOVED-LUG PAVING BRICK Application filed February 7,1928. Serial No. 252,571.

This invention relates to paving brick and has for its object theconstruction of a brick adapted to be laid in the pavement with the cutsurface uppermost, and having spacing lugs projecting from the dieformed surface thereof to space one brick from the next adjoining phaltor other suitable filling material w ll flow downward between the brickwhen laid in a pavement. These bricks are known as vertical fibergrooved lug paving bricks because the cut surfaces of said brick arelaid uppermost, and with the die formed surfaces vertical, adjoining thenext adjoining brick I in the course, with the projecting lugs on saiddie formed surface spacing the bricks apart.

he features of this invention are hereinafter fully set forth andexplained and are illustrated in the accompanying drawings in which:

Figure 1 is a side elevation of a column of clay as it emerges from thedie of the auger machine.

Figure 2 is a top or plan view of the same.

Figure 3 is a top plan view of a series of vertical fiber grooved lugpaving bricks according to my invention.

Figure 4 is an end view of Fig. 3.

Figure 5 is a section on the line 5-5 in Fig. 7 showing one means forforming the grooved lugs on the bricks.

Figure 6 is an end view of a series of the improved bricks with the edgemolds thereon, the latter being in sections.

Figure 7 is a section of the same on the line 6--6 in Fig. 5.

Figure 7 is a section of the same on the line 6-6 in Fig. 5.

Figure 8 is an end view of Flg. 6, looking in the direction of thearrow.

In these drawings A indicates a fragment of an auger machine, and Aindicates the die secured on said auger machine from which a column ofclay is forced in a continuous stream. The orifice in said die is soformed that the upper surface of said column has formed thereon threespaced ribs C, which are raised above the surface C of the column B. Theraised ribs C extend from the die A forwardly longitudinally of thecolumn B brick so that liquid cementor hot as and are transversely cutoff of the column,

as indicated by the broken lines D, by the cutting wires of the cuttingmachine, (not shown) so that said raised ribs C, will extend across theupper die formed surface C of each brick, and if the wire cut surface.of the brick are now laid up in a pavement, said raised die formed ribsC will separate said bricks so that fluid filler will fiow into saidspaces between said bricks and fill the same.

It has been found, however, that it is ad transversely of said ribs C,leaving a portion of said ribsremaining on each brick, which pro ectfrom the die formed surface C of the brick as grooved lugs G which lugsC will be uniform in length and will maintain said bricks separate fromeach other through the pavement.

In Figs. 5, 6, 7 and 8 I show one means for grooving the ribs C, andforming them into lugs in which F indicates a plate adapted to belowered upon the upper surface of the clay column B, said plate beingprovided with indentations 7 adapted to receive a portion of each rib Cthereinto, and press down the clay of said ribs outside of saidindentations, thereby leaving the clay entering said indentations,projecting to form said lugs C WVhile I have hereinbefore shown anddescribed a preferable mechanism for forming the lugs G I am aware thatthere are many other mechanisms adapted to accomplish the same result,therefore I do not desire to be limited to the mechanism herein shownand described, but what I claim as new and desire to secure by LettersPatent is:

A brick for use in pavements, comprising a substantially rectangularbody portion having wear resisting and tractive wire cut upper and lowerfaces and having relatively smooth and uninterrupted fiat edge and endfaces, said body portion having across one only of said edge facesspaced apart broad ribs and the brick adapted to be laid with said ribsabutting the opposite fiat edge face of a like prior laid brick toprovide vertical 11m grout filler receiving passages between the ribsand adjacent bricks When laid and hold the adjacent bricks fromlongitudinal relative movement, and said ribs having spaced depressionsextending thereacross and open ing into the vertical passages to admitfree horizontal flowing of the filler to anchor adjacent bricks againstrelative Vertical displacement.

In testimony whereof I aifix my signatnre.

JACOB NESSLY PORTER.
